Merge Mode Comparison
Each of the three merge modes produces different results. Choosing the right one better meets your actual needs. The table below compares them in detail:
| Merge mode | Result | Best for |
|---|---|---|
| Files → Sheets | Each file becomes an independent worksheet, with the file name as the sheet name | Scenarios that need clear data sources with separate file management |
| Files → Single sheet | All files' data is appended to the same worksheet | Consolidating multiple identically structured datasets into one master table |
| Sheets → Single sheet | All worksheet data is merged into one table regardless of file boundaries | Consolidating data across multiple workbooks/worksheets |
